I have been bonded with Ghost Bond for a week now and it still looks great and I have no 'dirty forehead' issues. I've had to do very minor touch ups twice, but nothing major. Like 20 seconds max. One thing I did notice was that from reading about Ghost Bond, it is very important to apply the right amount of coats and let each dry the way it was intended. What they want you to do it apply a coat then let it go clear, then apply the next coat. When you have the proper amount of coats they want you to let it sit for 7 minutes. I followed to the letter and my results have been good.
